EN-2 Defender Series Floor Scale
1. Introduction
This manual contains installation, operation and maintenance instructions for
the Defender series floor scale.
1.1. Safety Instructions
Please follow these safety precautions:
Position the power cord so that it does not pose a potential
obstacle or disconnection hazard.
Operate the equipment only under ambient conditions specified in
the user instructions.
Disconnect the equipment from main power before cleaning or
servicing.
Do not operate the equipment in hazardous or explosive
environments.
The foundation at the installation site must be capable of safely
supporting the weight of the floor scale plus the weight of the
maximum load.
Ensure vibrations around the scale are kept to a minimum. This
also applies to transportation.
Service should only be performed by authorized personnel.

1.2. Connecting an Indicator
When connecting the base to TD52 indicator, push the base connector onto the
indicator connector and turn the locking ring clockwise to lock it in place.
When connecting the base to an indicator that does not have the matching
connector, install the optional load cell cable adapter (P/N 30429931 sold
separately) to the indicator. Then attach the load cell cable to the cable adapter.
Note: As an alternate wiring method, cut off the connector, strip the wires and
attach them to the indicator using the wiring codes in Table 1.
The extension cable accessory (P/N: 30429931) cannot be used if the scale will
be used in a legal for trade or legally controlled application, because there is no
provision to seal the connection between the indicator and platform.

2. Internal structure and working principle

Defender Series Floor Scale EN-5
DFL series clamshell floor scale are made up of components demonstrated
above. Connect the double shielded cable to the weighing instrument and turn
on the power to use. In addition, external devices such as big screens,
computers and printers can be connected to the scale.
2.2. Working principle
Put an object on the weighing platform. Under gravity, the load cell elastomer
deforms and makes the impedance of the strain gauge bridge adhered to the
elastomer by the strain gage out of balance. As a result, a voltage signal
proportional to the weight value is outputted. The signal is then amplified by a
linear amplifier, and converted to a digital signal by an analog-to-digital
converter, which is processed by the microprocessor of the meter to display
the weight data. Squadron staff can read the weight directly and print weight
record at any time if having a printer. You can open the scale to flush the
hidden areas at the bottom when clean.

3. Basic requirements and installation
3.1. Basic requirements
Ensure that the installation is performed according to the instructions, and the
surface is flat in the area where the scale will be positioned,
The Height difference of the surface must not exceed 1mm. The maximum
weight capacity of the surface at the four cell feet position should be higher
than the maximum allowed weight of the cell.
3.2. Standard installation
1. Unpack the wooden box and take out the product. Remove all packages.
2. Choose an installation location. Place the weighing platform on the
ground and connect it with the ramp. Whole scale positioning (as shown
below).

3. Lift the weighing platform and buckle the safety buckle to prevent the
scale from falling. Check the location of the eight expansion bolt holes on
the bottom frame of the scale body and the mounting feet at this time,
and install the expansion bolts to the ground (note: the expansion body
must be installed before closing the scale body, otherwise the bottom
frame will be deformed).

4. Release the safety buckle and close the scale body. Adjust the height of
the sensor connector to ensure that the connector is stable on the
ground, and at the same time screw the knob to the end.
